Brush-Footed Butterflies You Will See Often

This family is the largest group of butterflies. They have short, hairy front legs that look like little brushes. Many of them are medium to large in size.

Monarchs migrate to Mexico every year. In Iowa, you will see them passing through in September. They are a sure sign of late summer.

Look for the two eyespots on the bottom of the hindwing. That is the easiest way to tell it apart from the Painted Lady.

Viceroy

The Viceroy looks a lot like the Monarch, but it is smaller. It has a black line across the hindwing that the Monarch does not have. It is a mimic that benefits from the Monarch’s bad taste to predators.

Where To Find These Butterflies In Iowa

You do not need to go to a special park to see butterflies. Many species live right in your backyard. Here are some of the best places to look.

Your Own Garden

Planting native flowers is the best way to attract butterflies. They need nectar for food and host plants for laying eggs. A simple garden with a few key plants can bring in many species.

Plant milkweed for Monarchs
Plant asters for Pearl Crescents
Plant clover for Sulphurs and Blues
Leave some nettles for Red Admirals and Commas
Provide a shallow water source

Even a small container garden can work. Butterflies are not picky. They will find your flowers if you plant them.

Roadsides And Ditches

Roadsides are often overlooked, but they are great butterfly habitats. They are full of wildflowers like goldenrod, thistle, and milkweed. Be careful of traffic when looking.

Many common species like Painted Ladies and Sulphurs use these areas. They are easy to spot from a slow-moving car. Pull over safely to get a closer look.

Prairies And Nature Preserves

Iowa has many restored prairies. These are excellent places to see a wide variety of butterflies. You will find species like the Regal Fritillary (less common) and many skippers.

Visit in late summer for the best diversity. The flowers are in full bloom, and butterflies are abundant. Bring a camera and a field guide.

Parks And Greenways

City parks with natural areas are good spots. Look along trails and near water. You will see many of the common species listed above.

Greenways that connect natural areas are especially good. They act as corridors for butterflies to move through the landscape. Walk slowly and watch for movement.

How To Identify Butterflies Quickly

Identifying butterflies can be tricky at first. Here are some tips to make it easier. You will get faster with practice.

Look at the size: Is it tiny (less than 1 inch) or large (over 3 inches)? Size is a good first clue.
Check the color: Is it orange, yellow, white, or blue? Many species have a dominant color.
Notice the pattern: Are there spots, stripes, or eyespots? Look for unique marks like the Viceroy’s black line.
Watch the flight: Does it fly fast and straight, or slow and bouncy? Skippers fly erratically, while Monarchs glide.
Look at the wings: Are the edges smooth or ragged? Ragged edges are common in Commas and Question Marks.

Take a photo if you can. Then compare it to a reliable source. There are many good apps and websites for butterfly identification.
